CFrame + CFrame?
Just wondering, why is it CFrame * CFrame for adding positions? Why not:
Something.CFrame = Something.CFrame + CFrame.new(0,10,0)
Instead of:
Something.CFrame = Something.CFrame * CFrame.new(0,10,0)
Just curious, thanks for reading.

Not in terms of position. You add 2 CFrame positions by multiplying them. My question is, why? LuaQuest 450 — 8y

If you want to add a position you would add a Vector3.
Something.CFrame = Something.CFrame + Vector3.new(0,4,0)
This just modifies the position and ignores rotation completely.
When you multiply two CFrame values, you're transforming based on the first CFrame's rotation. In other words, if I have a rotated part, multiplying the part's CFrame by CFrame.new(0,4,0) will move the part 4 studs up relative to the old CFrame, whereas just adding a vector will move it up by 4 studs.
